Mawu Oyamba
3-Nitro-5-bromobenzoic acid (3-Bromo-5-nitrobenzoic acid) ndi organic pawiri ndi mankhwala chilinganizo C7H4BrNO4. Zotsatirazi ndizofotokozera za katundu, ntchito, kukonzekera ndi chitetezo cha pawiri:
Chilengedwe:
-Maonekedwe: 3-Nitro-5-bromobenzoic asidi ndi kuwala chikasu olimba.
- Malo osungunuka: pafupifupi 220-225 ° C.
-Kusungunuka: Kusungunuka kochepa m'madzi, koma kusungunuka mu zosungunulira monga ethanol, chloroform ndi dichloromethane.
- asidi ndi zamchere: ndi asidi ofooka.
Gwiritsani ntchito:
-3-nitro-5-bromobenzoic asidi nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe organic ndi ntchito yokonza mankhwala ena.
-Atha kugwiritsidwanso ntchito pokonza zinthu monga mankhwala, utoto ndi zokutira.
Njira Yokonzekera:
Kukonzekera kwa 3-nitro-5-bromobenzoic acid kumatha kumalizidwa ndi izi:
1. 3-nitrobenzoic asidi analandira ndi zimene asidi benzoic ndi asidi nitrous.
2. Pamaso pa ferrous bromide, 3-nitrobenzoic acid imayendetsedwa ndi sodium bromide kuti ipeze 3-nitro-5-bromobenzoic acid.
Zambiri Zachitetezo:
3-Nitro-5-bromobenzoic acid nthawi zambiri imakhala yotetezeka pakugwiritsa ntchito bwino komanso kusungidwa. Komabe, zinthu zotsatirazi ziyenera kukumbukiridwa:
-Pewani kukhudzana ndi khungu, kutulutsa mpweya komanso kuyamwa panthawi yogwira ntchito.
-Valani zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zishango zakumaso mukazigwiritsa ntchito.
-Mukakumana ndi pawiri, sambitsani nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala.
-ziyenera kusungidwa kutali ndi moto ndi okosijeni, pamalo ozizira, owuma.
Zindikirani: Zomwe zili pamwambazi ndizongogwiritsa ntchito. Chonde tsatirani malamulo okhudzana ndi chitetezo mukamagwira ntchito mu labotale, ndipo funsani zidziwitso zachitetezo chapagululi ngati kuli kofunikira.
